In that case, the effect differs depending on the hardware. In the ideal 
universe, Thinkpad users flick out the eject lever and wait for a 
confirmation that they can pull out the drive. Dell and HP users have to 
request a safe remove in advance.

Right. In that case, it needs to be possible for userspace to indicate 
that the eject request should not automatically destroy the device. 
Actually removing the dock should do so in all circumstances.
